Zero Day Vulnerabilities
The first two flaws mentioned were actively exploited.
CVE-2024-43573: Windows MSHTML, Platform Spoofing, CVSS 6.5 – The MSHTML platform was previously used by Internet Explorer and the Legacy version of Microsoft Edge, and its components are still present in Windows. According to Microsoft, the MSHTML platform is used by Internet Explorer mode in Microsoft Edge and other applications through web browser control.
Though unconfirmed, this issue may bypass a previous vulnerability that exploited MSHTML to spoof file extensions in alerts shown when opening files. A similar MSHTML spoofing vulnerability was disclosed last month, where attackers used Braille characters in filenames to disguise PDF files.
CVE-2024-43572: Microsoft Management Console, Remote Code Execution, CVSS 7.8 – This vulnerability enabled malicious Microsoft Saved Console (MSC) files to execute remote code on affected devices, and the fix involved blocking untrusted MSC files from being opened.
Though this flaw is known to have been actively exploited in attacks, the method used remains unclear.
CVE-2024-6197: Open Source Curl, Remote Code Execution, CVSS 7.5 – This vulnerability is in libcurl and could allow commands to be executed when Curl connects to a malicious server that presents a specially crafted TLS certificate. The fix involved updating the libcurl library, which is included with the Curl executable in Windows.
CVE-2024-20659: Windows Hyper-V, Security Feature Bypass, CVSS 7.1 – This UEFI bypass vulnerability which affects virtual machines could allow attackers to compromise both the hypervisor and the secure kernel. An attacker would need physical access to the device and must reboot it to exploit the vulnerability.
CVE-2024-43583: Winlogon, Elevation of Privilege, CVSS 7.8 – This privilege escalation vulnerability could allow attackers to gain SYSTEM-level access on Windows devices. Mitigation steps involve keeping a Microsoft first-party Input Method Editor (IME) enabled, preventing the exploitation of any vulnerabilities related to third-party IMEs.
